CX brief for the classic is 1.18 EPR, and 3 NU for 280 knots, I don't remember them giving anything for 250 kts, although Qantas suggest 5 NU (I did a practise sim there).
For information the CX brief suggested 1 NU for the approach (Flap 30), EPR to stay at 1.18. It worked last week!
-400 bit more thrust - might well be different I guess.
Hope that helps a bit,
